Method Detail

isFatalEnabled

public boolean isFatalEnabled()

Description copied from interface: Log

Is fatal logging currently enabled?

Call this method to prevent having to perform expensive operations (for example, String concatenation) when the log level is more than fatal.

Specified by:

isFatalEnabled in interface Log

Returns:

true if fatal is enabled in the underlying logger.

isErrorEnabled

public boolean isErrorEnabled()

Description copied from interface: Log

Is error logging currently enabled?

Call this method to prevent having to perform expensive operations (for example, String concatenation) when the log level is more than error.

Specified by:

isErrorEnabled in interface Log

Returns:

true if error is enabled in the underlying logger.

isWarnEnabled

public boolean isWarnEnabled()

Description copied from interface: Log

Is warn logging currently enabled?

Call this method to prevent having to perform expensive operations (for example, String concatenation) when the log level is more than warn.

Specified by:

isWarnEnabled in interface Log

Returns:

true if warn is enabled in the underlying logger.

isInfoEnabled

public boolean isInfoEnabled()

Description copied from interface: Log

Is info logging currently enabled?

Call this method to prevent having to perform expensive operations (for example, String concatenation) when the log level is more than info.

Specified by:

isInfoEnabled in interface Log

Returns:

true if info is enabled in the underlying logger.

isDebugEnabled

public boolean isDebugEnabled()

Description copied from interface: Log

Is debug logging currently enabled?

Call this method to prevent having to perform expensive operations (for example, String concatenation) when the log level is more than debug.

Specified by:

isDebugEnabled in interface Log

Returns:

true if debug is enabled in the underlying logger.

isTraceEnabled

public boolean isTraceEnabled()

Description copied from interface: Log

Is trace logging currently enabled?

Call this method to prevent having to perform expensive operations (for example, String concatenation) when the log level is more than trace.

Specified by:

isTraceEnabled in interface Log
